Set the gravity of an element when zooming?

Question

I'm injecting an iframe into a webpage, to act as a toolbar for another element, but unfortunately the elements act weirdly when zooming. The toolbar seems to gravitate towards the topleft corner, and the element towards the top-center. This means when zooming in they go into each other, and when zooming out they go way too far apart. is there any way to set this gravity?

我希望看到一个jsfiddle，所以我确切地知道您想要什么，但是只使用固定位置即可。
